Be it knownthatl, CARLO BoRGHEsE, as'ubof Italy, residing at Turin,Italy,have `invented certain new and useful Improvements in AutomaticRailway- Signals, of which the following is aspecilication.

This invention relates to the class of railway signaling devicesdesigned to operate a train to warn, the engineer when a particularpoint is reached by the train. The signal produced by the presentinvention may be Visual or acoustic, but the latter is preferred. Thesignal may be employed in conjunction with, or as a substitute for theordinary signals, and it may be emoroperate the conti'nucns brakes on a'passing train.l

The invention comprises as its essential features two devices, one ofwhich is placed on the track and the other carriedV by the 'movingtrain. The device placed on they track is in the nature of ,an obstacle,which may be either fixed in a permanent manner at some particularpoi-nt on the track, or be adapted to be tixed hurriedly in a temporarymanner to a rail, a `lleeper, or some .ther convenient part of thetrack. l The derice carried by the train, and perhaps most convenientyby `the locomotive drawingthe with means sleeper, or

4ate' the corresponding train. is designed to produce the signal by itsen counter withthe obstacle on the track when stacle secured in place onthe track may have various forms to -suit the circumstances so long asit isadapted to encounter and actudevice on the train. Itmay,-as stated,be portable, and vprovided for quickly fixing it to a rail or be set inplace-in a permanent manner. lnthe latter case, it may be pro.-

;vided with,or combined with means for .op-

a distance, as in the case. of

erating it from acoustic signaling devices.

other visible or The device carried by the train may be iixed on thelocomotive, forexample, at any point where it willv encounter theobstacle on the track. The signals'voperated by the device may be ofvaried kinds, optical, acoustic, &c.; itwill serve to employ anacousticsignal loud enough to ,be easily heard -by the engineer and trainmen.lThis signal may be a whistle,

The obvice to a block signal systemjis the obstacle or devicespectively,

an electric bell, a steam or compressed air signal, &c. ln ordinarycases where the device is mounted on the locomotive, it will be connvenient to employ a steam whistle as a signal, 5 5v but it is preferableto employ another than the regular whistle of the locomotive.

tially of a cock or valve l), and a pendent 8o signal operating armorlever E, which is secured to and controls the oscillating plug of thecockand swings in a vertical plane-parallel with the track. The lowerend `ot the arm E, is furnished with cushions e, e, of rub- Aber or thelike to ameliorate the shock when the arm encounters the obstacle A.1fixed' box, d, ofthe cock D, has two opriesitely arranged ports, incommunication, re

through pipes steamboiler or compressed air reservoir on the'one hand,and with a Whistle,or otheranalogous signal, on ythe other hand, thecock D cutting oit the communication, normally," between said boiler h,of the cock l), is not pierced as usual, but has a circumferentialgroove, t', which extends nearly around the plug with one of the pipes(G inI Fig. 2) at all times, and whenever the arm E, is swung toroo wardeither side of the perpendicular alittle' way, one orthe other extremityofthe groovefixed on the track. l7o

On the upright l 'F and G, with a 9od and whistle. `The plug andis inconnection j 'i will communicate with the other pipe (F in Fig. 2).When the cushion e on the end of the arm E encounters the obstacleA,when passing, in which ever direction the train may be moving, the armwill be Yswung to one side and the alarnrsounded, and the alarm willcontinue to sound while the arm is displaced, thus warning the personnelof the train.' The arm E, Or the stem of the cock-plug, may have a cordor arm attached to it so that the engineer Or trainman can, ifnecessary, return the lever to its normal positiorandthe trainman mayascertain by this arm or device whether the arm E, is displaced in casethe signal does not sound. These parts are not shown in the drawings asthey are not indispensable and may be supplied by any good workman ifthey are needed.

I have shown one of the many ways in which the displacement of the arm Emay be made tO sound an acoustic signalhand I do not deem it necessarytoshow Otherways; it

fwill suffice' to say thatI the arm E, or some equivalent device, may bearranged to close a circuit through an ordinaryelectric bell. This couldbe effected by any o ne with'solne knowledge of electricity. 4 l

Fig. l, as I have said, showsan obstacle A adapted to be attachcdto thetrack rail at any point, and in a temporary manner;` and in Iig.` 3 Ihave shown how the obstacle may be secured in place in a permanentmanner and b'e set to operate, or so aste be inoperative or inert, froma distant point. In this figure; a base-piece, M, embraces the foot ofthe rail and is secured tothe web of the rail by a bolt andthe obstacleA is hinged or pivoted to the base-piece at m, so thatit may belet downto the position seen in dotted lines, when its crown will not be inposition to encounter the arm E On a passing-train. Onthe ObstacleA isan arm Z, to which is coupled an operating rod, n, which may extend to aconsiderable distance from the point where the obstacle is placed n thetrack. This type of the device is best suited for fixed installations,and is well adapted for use with disk or semaphore signals of the usualkind. In such a case the saine roth/n, may set the semaphore and theobstacle A,and the engineer will then receive an acoustic signal at thesame time that the semaphore is displayed. It will only require ordinaryskill and judgment to furnish themechanical details to adapt the'signalto dierent situations and-different roads.

It will be understood that my device as herein shown may be employed toset'the brakes 0f a passing train,'and particularly the Ordinarycontinuous compressed air and vacuum brakes. In this case' it will onlybe necessary to suppose the pipes F and G to represent the train-pipe,and the valve D to represent the ordinary train-valve or an analogousvalve. The setting of the brakes will be a signal to the engineer andthe trainmemalthough not, in the Ordinary senso, either auy acoustic orvisible signal.

My improvements are adapted to any system of signal service on railways,either the block system or other systems, and as well to double track,as to single track roads. For example, as seen in Fig. 4, P and Q aretwo successive stations; p and q are the two signaling posts nearestthese stations on the main line. Iam able to establish that when thestation P should send a train toward station Q, it warns it and at thesame time warns the post q to set its obstacle so as to arrest; thestation Q, responding, notifies the post 1J to ope-n the line to itstower. It will thus be seenthat the line will only be Open when the twostations are in accord. It' each post closes the line after the passageof the train until further orders, each train remains blocked and alldanger is avoided. y

Having thus described my invention, I

claim- 1.-- In a railway signal, the combination with a movable obstacleon the track, of the signaloperatiug arm E, carried by the locomotive orcar, said lever having a yielding cushion, e, at

the point where it impinges upon the-'obstacle4 set on the track,substantially as set forth.

' 2. In a railway signal, the combination with la movable obstacle onthe trackliaving an arched Or rounded crown, of the signal-operating armE, carried by the locomotive or car, said lever having a yieldingcushion e, with a. convex or rounded surface at the'point where itimpinges upon the obstacle set on the track, substantially as set forth.
